not much on the probability of getting exactly one 4 on four rolls of a die
Answer:
you need to subtract
Step-by-step explanation:
Answer:
Expression: 48x + 120y & Area = 1,008 square feet
Step-by-step explanation:
12(4x + 10y)
multiple the 12 into 4x + 10y
12 x 4x = 48x
12 x 10y = 120y
48x + 120y
x = 6 ft
y = 4 ft
Substitite in numbers
48x + 120y
48(6) + 120(6)
Multiply
288 + 720
Add
288 + 720 = 1,008 square feet
Answer: correct option is A
0.100
Step-by-step explanation:
Given that
population = 500 elements.
To draw a simple random sample of 50 elements from this population. On the first selection
The probability = 50/500 = 0.1
The probability of an element being selected is 0.100
<span>2cos^2x = sin2x
2cos^2x = 2sin x cos x
(2sin x cos x) / (2cos^2x) = 1
sin x / cos x = 1
tan x = 1
x = π/4</span>
